Specification of Letters Patent.

Patented March 19, 1907.

Application filed April 9, 1906. Serial No. 310,875.

especially adapted for lubricating the bear-.

in s of Windmills, but also adapted for use in lu ricating the bearingsof other kinds of machinery; and it consists in the construction,combination, and arrangement of devices hereinafter described andclaimed.

In the accompanying drawings, Figure 1 is a vertical sectional view ofalubricator embodying my invention, and Fig. 2 is a detail elevation.Fig. 3 is a detail plan view of the worm or spiral gear.

In accordance with my invention I provide a can or reservoir 1 to hold auantity of oil or other suitable lubricant. Said can or reservoir ishere shown as supported by a standard rod 2, which extends upwardly fromthe bearing 3 for the shaft 4 of a windmill. The said shaft is hereshown as rovided at one end with a crank-wheel 5, to the crank-pin 6 ofwhich is attached the usual pitman-rod 7. In the lower portion of thereservoir is a bracket 8, having a lower horizontal arm 9, which bearson and is secured to the bottom of the reservoir, and an upper arm 10,having a stud or other bearing 11, on which rotates a disk 12. The saiddisk is provided on its up er side with ratchet-teeth 13 and is provideon its lower side with a worm 14. A worm wheel or gear 15, which has itsbearing 16 on one side of the bracket 8, is engaged by the said worm 14,sothat the said gear 15 is partly rotated to the extent equal to thespace between two of its teeth or spurs at each rotation of the disk 12.The latter is rotated by a step-by-step movement by means of anoscillating rod 17, which is here shown as having its bearings at 18 inone side of the reservoir, near the upper end thereof, and as providedwith a depending inner arm 19, having a dog 20, which successivelyengages the teeth 13 of the disk 12 and turns said disk to a slightextent equal to the space between two of the said teeth 13 at eachmovement of said oscillating rod 17.

Any suitable means may be employed to operate the said oscillating rod.For the purposes of this specification it is shown as operated by a rod21, which has an eccentricstrap engaging the periphery of the crankwheel5, the latter being eccentrically mount ed on said shaft 4.

A cylinder 22 depends from the reservoir 1. A tube 23 extends downwardlyin the said cylinder 22 for a suitable distance and also extends for asuitable distance up from the bottom of the reservoir. The upper andlower ends of the said tube are open and are respectively provided withslots 24 25 of suit able length, which form channels for the escape oflubricant from the reservoir 1 and the tube 23, as hereinafterdescribed. The channels 24' extend from the upper end of the tube 23down to the level of the bottom of the reservoir. The channels 25 in thelower end of said tube are of the same length as said upper channels 24.

A pair of valves 26 27 operate simultaneously in the tube 23 and areconnected together by a rod 28. Nuts 29 are here shown screwed on saidrod and clamped against the up er and lower sides of the said valves tohoid the latter in place on the rod. A itman 30 connects the upper endof the va verod to a wrist-pin 31, with which the gear- Wheel 15 isprovided. The said valves are so spaced apart that when they are at theupper llmit of their movement the channels 25 will be closed by thelower valve 27, while the extreme lower ends of the channels 24 will beopened to a very slight extent by the upper valves 26. When the saidvalves are at the lower limit of their movement, the u per ends of thechannels 25 will be slight y opened by the lower valve 27 to permit theescape of oil from the tube 23 into the cylinder 22, the upper valve 26controlling the escape of oil from the reservoir into the said tube 23.It will be understood that the said valves will be moved by the actionof the gear 15 and the pitman 30.

The oil from the cylinder 22 is led through suitable tubes 32 to thevarious bearings of the windwill or'other machine. Where the bearing isa movable one-as, for instance, in the case of the pin 6the tube 33,which leads from the cylinder 22, terminates short of the bearing 6, anda spring-coil 34, made of wire or other suitable material, connects thelower end of said tube 23 to the said movable IIC -: reservoir,simultaneously-movable valves to bearing. This spring-coil, whileserving to conduct the oil from the tube 33 to the movable-bearing,yields and accommodates itself to the movement of the said bearing. Itwill be understood that the mechanism in the can or reservoir 1 iscovered by the oil or other lubricant in the said reservoir.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion, andthe minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claims.

Having thus described my invention, what I' claim as new, and desire tosecure by Letters Patent, is

1. In a lubricator, the combination of a control the dischargeoflubricant therefrom, a gear-wheel in said reservoir, a connectionbetween said gear-wheel and said valves to operate the latter, a disk insaid reservoir having a worm engaging said gear-wheel and i alsoprovided with ratchet-teeth, a rocking element, and a dog carriedthereby to engage said ratchet-teeth for the purpose set forth.

2. In combination with means to discharge a lubricant, a movablebearing, a tube leading from said lubricant-discharging means, and aspring-coil connecting the lower end of said tube to said bearing, forthe purpose set forth.

3. In a lubricator, the combination of a reservoir, a cylinder extendingdownwardly therefrom, a tube with its upper end in the lower portion ofthe reservoir, its lower end in the cylinder, and having vertical slotsin its upper and lower ends, a pair of valves in said tube, coactingwith theslots thereof to permit oil to pass from the reservoir into thetube and from the-latter into the cylinder, means to simultaneouslyreciprocate the said valves, and means to adjust the valves toward andfrom each other to vary the quantity of oil discharged by thelubricator.

In testimony whereof I have hereunto set my hand. in presence of twosubscribing witnesses.
